中国的二氧化碳边际减排成本

China's marginal carbon abatement cost for 2010 through 2050 was studied using the China MARKAL-MACRO model, an integrated energy, environmental, and economic model to provide a scientific basis for the formulation of policies and strategies to respond to climate changes in China. Mathematical functions are given for the marginal carbon abatement cost curves for 2010, 2020, 2030, 2040, and 2050. The analysis also evaluates the impacts of different carbon abatement strategies, starting times, and nuclear power development limits on the marginal carbon abatement costs. The modeling results show that the marginal carbon abatement cost in China is quite high, in the range of 0-250 USD/t for reduction rates of 0%-45%. In addition, the marginal abatement cost will increase for the same amount of carbon reductions if the carbon reduction obligations are initiated sooner. Limits on nuclear power development will further raise China's marginal carbon abatement cost.
